Abstract

Claims (25)

1 . A cartridge for use in an aerosol delivery device, the cartridge comprising:

an outer housing configured to contain at least an aerosolizable composition, the outer housing including an exit portal at a proximal end thereof for passage of an aerosol; and

a bottom cap positioned at a distal end of the outer housing that is configured for insertion into a receiving chamber of a control device of the aerosol delivery device;

wherein the outer housing defines a front face portion and a rear face portion interconnected with sidewalls such that the outer housing has a width defined between the sidewalls and a thickness defined between the front face portion and the rear face portion, the width being greater than the thickness;

wherein the outer housing defines a ledge that encircles the front face portion, the rear face portion, and the sidewalls;

wherein the ledge extends further down the front face portion than the rear face portion, such that the front face portion has an asymmetrical configuration relative to the rear face portion;

wherein the asymmetrical configuration of the ledge defined by the outer housing is effective such that the cartridge engages the control device of the aerosol delivery device in only a single orientation; and

wherein the ledge has a substantially U-shape on the front face portion and a substantially linear shape on the rear face portion.

2 . The cartridge of claim 1 , wherein the outer housing comprises a mouthpiece situated at the proximal end of the outer housing, and wherein the exit portal is defined through the mouthpiece.

3 . The cartridge of claim 2 , wherein the mouthpiece comprises the rear face portion and the sidewalls of the outer housing.

4 . The cartridge of claim 3 , wherein the outer housing further comprises a central housing portion including a viewing window.

5 . The cartridge of claim 4 , wherein no portion of the viewing window is defined by the control device.

6 . The cartridge of claim 4 , wherein the viewing window is transparent.

7 . The cartridge of claim 1 , wherein the outer housing comprises a viewing window.

8 . The cartridge of claim 7 , wherein the viewing window is transparent.

9 . The cartridge of claim 7 , wherein at least a portion of the aerosolizable composition is visible through the viewing window.

10 . The cartridge of claim 1 , wherein the bottom cap is configured to engage a distal end of the outer housing.

11 . The cartridge of claim 1 , further comprising a heating assembly configured to heat the aerosolizable composition to generate an aerosol.

12 . The cartridge of claim 1 , wherein an aerosol path is defined through the outer housing and the exit portal.

13 . The cartridge of claim 1 , wherein at least a portion of the rear face portion is covered by a back wall of the control device when the cartridge is engaged with the control device, such that a larger portion of the front face portion is visible than the rear face portion.

14 . The cartridge of claim 1 , wherein the ledge protrudes outwardly from the outer housing.

15 . The cartridge of claim 14 , wherein the outer housing is configured to engage the bottom cap.

16 . The cartridge of claim 1 , wherein the front face portion of the ledge at least partially defines the shape of a viewing window.

17 . The cartridge of claim 16 , wherein no portion of the viewing window is defined by the control device.

18 . The cartridge of claim 1 , wherein the front face portion of the ledge is configured to partially cover a front side portion of the bottom cap.
